AIM:To measure the difference of intraoperative central macular thickness(CMT)before,during,and after membrane peeling and investigate the influence of intraoperative macular stretching on postoperative best corrected visual acuity(BCVA)outcome and postoperative CMT ***:A total of 59 eyes of 59 patients who underwent vitreoretinal surgery for epiretinal membrane was *** with intraoperative optical coherence tomography(OCT)were *** of intraoperative CMT before,during,and after peeling was ***-and postoperatively obtained BCVA and spectral-domain OCT images were ***:Mean age of the patients was 70±8.13y(range 46-86y).Mean baseline BCVA was 0.49±0.27 log MAR(range 0.1-1.3).Three and six months postoperatively the mean BCVA was 0.36±0.25(P=0.01 vs baseline)and 0.38±0.35(P=0.08 vs baseline)log MAR *** stretch of the macula during surgery was 29%from baseline(range 2%-159%).intraoperative findings of macular stretching did not correlate with visual acuity outcome within 6mo after surgery(r=-0.06,P=0.72).However,extent of macular stretching during surgery significantly correlated with less reduction of CMT at the fovea centralis(r=-0.43,P<0.01)and 1 mm nasal and temporal from the fovea(r=-0.37,P=0.02 and r=-0.50,P<0.01 respectively)3mo ***:The extent of retinal stretching during membrane peeling may predict the development of postoperative central retinal thickness,though there is no correlation with visual acuity development within the first 6mo postoperatively.

Feasibility and utility of intraoperative optical coherence tomography during vitreoretinal surgery:A 4-year report in Chinese population

Journal of Innovative optical Health Sciences 2021年第1期4卷 46-55页

The objective is to introduce the application of intraoperative optical coherence tomography(iOCT)in pars plana vitrectomy(PPV)for various vitreoretinal diseases,and to report the 4-year assessment of feasibility and utility in Chinese *** reported a retrospective case series of patients who underwent PPV and iOCT scan at Eye Hospital of Wenzhou Medical University from January 2016 to January *** characteristics were documented before operation,and we intraoperatively recorded the time and results of iOCT scanning,specific surgical maneuvers performed,the consistency with the planned strategies before surgery,the type of OCT images obtained,and adverse events(AEs).The surgeon feedback was collected to evaluate the utility of iOCT during *** total 339 eyes successfully completed iOCT scan,with an average scanning time of 3.54±2.3 min,including 59 cases of idiopathic macular hole(iMH),134 cases of idiopathic epiretinal membrane(iERM),33 cases of lamellar macular hole(LMH),40 cases of high myopic maculopathy,13 cases of vitreous macular traction(VMT),60 cases of dense vitreous hemorrhage(VH).The iOCT findings were not consistent with exami-nation under the operating microscope in 49 cases(14.5%),including 29 cases(8.6%)which changed the operation strategies during *** Hole-door phenomenon arose in 20 cases(33.9%)of iMH and 3 cases(25%)of high myopic MH after ILMs ***,the residue ERM was observed in nine cases(6.7%)of iERM and two cases(14.3%)in high myopic ERM after ILMs *** new surgical methods could also be confirmed using *** ap-plication of iOCT has a significant clinical functionality in vitreoretinal surgery,providing the surgeon with a new surgical understanding,guiding the selection of a more reasonable operative procedure during surgery,predicting postoperative recovery and improving postoperative outcomes.
